Four years after EP4, local prog-rock band Lackluster’s last official release, the band is back with an upcoming single titled “Rag and Bottle” and a release show. The band has gone through changes in both lineup and sound since EP4, and while the new track still maintains the same polished production as Lackluster’s previous music, there’s an edge this time around.

The background of guitar and bass are ultra-low and dark, and the slightest touch of fuzz adds a seriously pleasant resonance. Yet it’s not all the same throughout the track; the bridge has a warping, spacey melody that is quickly slashed through by a cutting guitar solo.

Frontman Jon Hayes croons mysteriously through faded vocals that blend perfectly with the rest of the dark-sounding music. Later in the chorus, though, autotune makes Hayes’s higher-pitched vocals sound chunky, contrasting nicely with the smoother instrumentals and adding a satisfying depth to the music.

Despite a dusky sound, “Rag and Bottle” is still catchy and has plenty of jam potential. Driving percussion ensures that nothing stays stagnant, and it feels impossible not to groove along with the glistening alt-rock melodies.

Lackluster plans to perform the single at a star-studded release show on Friday, Aug. 10. The band’s Facebook bio characterizes itself with a “power-packed show” with lasers and an innovative sound, and if “Rag and Bottle” is any indication, this one is no exception. As the band is accompanied by local favorites Urban Tropic and Silvis as well as Cleveland indie rockers Punch Drunk Tagalongs, the night is practically guaranteed to be a blast.

The show will take place at Spacebar. Doors open at 9 p.m., and there is a cover charge of $5 with an additional $3 charge for those under 21. The event is 18+.
